CX14SM AT CRYSTAL
Ultra-Miniature SMD Crystal
20MHz to 50MHz
FEATURES
Designed for infrared, vapour phase or epoxy mounting
Low profile, (<0.59mm) hermetically sealed ceramic
package
OUTLINE & DIMENSIONS
Excellent ageing characteristics
High shock and vibration resistance
Full military testing available
Available with glass or ceramic lid
DESCRIPTION
CX14SM crystals are designed for applications requiring very small
footprint and low profile (<0.59mm). Using micro-machining
processes this hermetically-sealed crystal ensures high stability and
low ageing.
